COSMETIC OR PERSONAL CARE FORMULATIONS CONTAINING POROUS METAL OXIDE SPHERES

The invention relates to a cosmetic or personal care formulation including a carrier and porous metal oxide spheres. The porous metal oxide spheres have,.eg., an average diameter of about 0.5 [mu]m to about 100 [mu]m and an average porosity of about 0.10 to about 0.80; the porous metal oxide spheres have one or more population of pores each having an average pore diameter, wherein each population has a different average pore diameter and wherein the average pore diameters are, e.g., from about 50 nm to about 999 nm. 本发明涉及一种化妆品或个人护理配制剂包括载体和多孔金属氧化物球体，其中所述多孔金属氧化物球体具有例如大约0.5μm至大约100μm的平均直径和大约0.10至大约0.80的平均孔隙率；所述多孔金属氧化物球体具有一个或多个孔隙群，各自具有一个平均孔径，其中各个群具有不同的平均孔径，并且其中平均孔径为例如大约50nm至大约999nm。
